Caution
■
Do not touch the terminals and connectors while the power is on.
Otherwise electric shock, malfunction or damage to the product can result.
■
Do not touch the piping or its connected parts when the fluid is at high temperature.
It may lead to burnt.
Ensure the piping cools sufficiently before touching.
■
After maintenance is complete, perform appropriate functional inspections and leak tests.
Stop operation if the equipment does not function properly or there is a leakage of fluid.
When leakage occurs from parts other than the piping, the product might be faulty.
Disconnect the power supply and stop fluid supply.
Do not apply fluid under leaking conditions.
Safety cannot be assured in the case of unexpected malfunction.

NOTE
○Follow the instructions given below when designing, selecting and handling the product.
●
The instructions on design and selection
(installation, wiring, environment, adjustment, operation,
maintenance, etc.)
described below must also be followed.
Product specifications
The direct current power supply to be used should be UL approved as follows.
Circuit (of class 2) which is of maximum 30 Vrms (42.4 V peak) or less, with UL 1310 class 2 power supply unit or
UL 1585 class 2 transformer.
The product is a UL approved product only if it has a
mark on the body.
Use the specified voltage.
Otherwise failure or malfunction can result.
Insufficient supply voltage may not drive a load due to a voltage drop inside the product.
Verify the operating voltage of the load before use.
Do not exceed the specified maximum allowable load.
Otherwise it can cause damage or shorten the life of the product.
Confirm the pressure loss at the sensor according to the flow rate characteristics (pressure loss) graph
before designing piping.
Confirm detection condition of sensor electrified potential.
The applicable fluids are water (0 to 90
o
C) and ethylene glycol solution with a viscosity of 3 mPa
s
(3 cP) or less.
Fluids other than those mentioned above will not be guaranteed.
Do not use fluids containing chemicals, synthetic oils, organic solvents, salt or corrosive gases.
Using such fluids can result in malfunction and damage to the product.
Check the details of the specifications before use.
Do not touch the piping or its connected parts when the fluid is at high temperature.
It may lead to burnt.
The rated pressure range and proof pressure vary depending on the fluid temperature.
Verify the specifications before use.
Consider measures to prevent over pressure due to water hammer.
<Measures to reduce water hammer>
1. Install a water hammer relieving valve.
2. Use a flexible material for piping (such as a rubber hose) and an accumulator that can absorb impact pressure.
3. Keep piping as short as possible.
Use the product within the specified operating pressure and temperature range.
Reserve a space for maintenance.
Allow sufficient space for maintenance when designing the system.
